There's an issue where the API docs for Homebrew https://www.rubydoc.info/github/Homebrew/brew are out of date and not rendering properly, even though they're being rebuilt according to the footer. Note how the Formula page doesn't recognize Markdown syntax at https://www.rubydoc.info/github/Homebrew/brew/master/Formula, and how recently-added modules like Cask aren't listed. (Everything works when I generate it myself with yardoc.) Not sure if this is related to how "Homebrew/brew" is still listed as an alternate fork for "brew" in the projects listing page: https://www.rubydoc.info/find/github?q=brew - it should be listed as the original fork. (And clicking the "reload" button there didn't help.)

Can you wipe and reload the docs for Homebrew/brew?
